Catheter Ablation of Recipient Right Ventricular Tachycardia after Heterotopic Heart Transplantation

Abstract

Ventricular tachycardia after heart transplantation. A case is reported of ventricular tachycardia (VT) in a 62-year-old male after heterotopic heart transplantation, who occasionally had attacks of palpitation. Surface electrocardiogram suggested VT arising from the recipient heart. Intracardiac electrograms and entrainment mapping confirmed macroreentrant VT located in the recipient right ventricle. Radiofrequency ablation using an electroanatomical mapping system (CARTO, Biosense Webster, Diamond Bar, CA, USA) successfully eliminated VT.

Ablation of Post-Myocardial Infarction Focal Ventricular Tachycardia

“…The EPS was carried out according to a classic protocol 2 . A quadripolar catheter (IBI Inquiry Irvin Biomedical Inc., St Jude Medical, Irvine, CA, USA) was placed on the right ventricular apex via the right femoral vein and a second 4‐mm tip‐irrigated catheter was inserted via the right femoral artery for ablation (Navistar Thermocool; Biosense‐Webster, Diamond Bar, CA, USA).…”
